Description
Technical field
[0001] the present invention relates to a kind of rotor unit that is used for whizzer, this whizzer comprises: non rotatable housing (described rotor unit is arranged in the housing to rotate); And comprise parts that at least some are made by metal; Be used to supply the inlet of the liquid mixture of the multiple composition that will separate; Be used for the outlet of separated during operation composition with at least one, this rotor unit comprises thus:
-separation chamber, it is formed in the rotor unit;
-inlet, it is connected to inlet and is connected to the separation chamber, and this inlet radially is formed in the described separation chamber and usually itself and separation chamber's protection is opened;
-at least one outlet, be connected to this separation chamber and
-a plurality of separator disks, with the coaxial described separation chamber of pivot center in axially-spaced one determining deviation setting each other.
Background technology
[0002] whizzer of above-mentioned described type example can be referring to WO90/04460.In that whizzer, partition wall by the potted component form is opened inlet and separation chamber's protection, if described potted component is arranged in the groove in the separator disk or separator disk and potted component are integrated by plastics manufacturing and each separator disk.Except operating a large amount of separator disks, if potted component is for example by the elastomeric material manufacturing, when operating more multi-part, the potted component that is arranged in the groove in the separator disk can cause following problems: these parts will wear and tear easily, and must periodic replacement.Consider the intensity of separator disk, integrated and can have limitation with each separator disk by the potted component of plastics manufacturing.The material behavior of dish and sealing device defines the application that can use whizzer equally.
[0003] general fashion that the rotor part of the above-mentioned type is fixed together is by being threaded they to be engaged with each other, can be with reference to WO90/04460.Separator disk is gone up in place by bar is firmly fixing, and by the tool of compression compression, to increase the rigidity of the separator disk that assembles.Compression to separator disk presses together them, and the symmetry that too much influences them thus of extruding and mutual location may cause imbalance thus, and this may be dangerous when rotor rotation.
Summary of the invention
[0004] the objective of the invention is to eliminate above-mentioned problem and a kind of rotor unit of dynamic stability of the rotation that is used for whizzer is provided, the validity of separation will be kept or improve to this rotor unit.
[0005] another purpose provides a kind of rotor unit that is used for whizzer, because the minimizing of the quantity of the separation assembly of whizzer, so this rotor unit is easy to installation and removal.
[0006] these purposes realize that by the device of introducing in the beginning part this device is characterised in that: at least some dismountable the linking together in the described metal parts of described rotor unit, and to form assembly.
[0007] according to embodiments of the invention, rotor unit comprises the parts by being welded together.
[0008] parts of rotor unit are welded together means in identical space and can adopt thinner separator disk, make and adopt more separator disk to become possibility, increased the validity of separating thus.
[0009] cement of material can be a corrosion-resistant solder in welding, and this scolder has than the better feature of ordinary solder.Corrosion-resistant solder has for example been eliminated the etching problem in the whizzer.The example of adoptable other scolder is based on the scolder of copper, nickel or iron.The component of the scolder that is fit to and the example of feature for example occur in WO02/38327 or WO02/098600A1.
[0010] according to still another embodiment of the invention, this rotor unit comprises parts, and wherein scolder constitutes the partition wall between inlet and the separation chamber in an easy manner.This scolder separates walls also causes producing more uniform pressure drop in the intermediate space between the separator disk, and causing in the intermediate space of separator disk better, fluid distributes the therefore separation that produces better degree.
[0011] separator disk is an example of the parts that can link together by scolder, but can also have the parts that are arranged on the porch and are used to supply the liquid mixture that will separate, be arranged on the parts that the exit is used for separated composition, carries element etc. secretly.
[0012] separator disk can they radially inside and/or their non-removable linking together in outside place radially.At their inside edge places radially separator disk being linked together causes the formation of partition wall, and this is representing the boundary between above-mentioned inlet and the separation chamber.Intermediate space between the separator disk can lead to the space between rotor unit and the nonrotational shell all around, if but separator disk is along linking together at their outer ledge places radially around pivot center, seam in each intermediate space forms partition wall, and they constitute rotor case together.By welding described separator disk linked together and to cause the formation of firm and stable rotor unit.
[0013] as mentioned above, the parts of outlet also can be connected on the separator disk, to form integrated unit.In these cases, this outlet for example can comprise the element with the conic section form of separator disk, and this element is by inside lengthening and be arranged on the suitable axial plane with respect to inlet radially.Outlet also can comprise one or more end plates that are arranged on an end place of separator disk lamination, with a kind of outlet in the liquid component that is formed for separating.Be joined together to form among the embodiment of even assembly by outlet device replacement according to the present invention and separator disk at common outlet device, can utilize this space more efficiently, can increase the quantity of the separator disk in the rotor unit thus, strengthen separative efficiency.
[0014] according to still another embodiment of the invention, rotor unit comprises the parts by being welded together.In this case, the described partition wall of the same formation of welding.
